VVEED BURNE‘R—NORTHERN PACIFIC RAILWAY.

The weed burner, shown by aid of these engravings, was de-
signed and built by the Motive Power Department of the
Northern Pacific Railway, and we are informed that it burns
"ordinary we-eds that grow along the tracks at a cost of from $2
to $4 per mile, and it will burn about 30 miles per day. The
saving efiected over hand labor in cutting weeds by a shovel
is about  per mile.

The burning outfit is carried on a flat-car, pushed by an eight
wheel locomotive, that is especially detailed for this service
during the season. The fuel for the burner is oil and the flame
is made most -effective by an air blast. There are 18 burners
carried in a growp on a frame hinged to the front end of the
car. There are six burners outside of each rail, and six burn-
ers between the rails. The frame is ordinarily held so that
the shield surrounding the burners is three inches from the
rails, but it may be raised out of the way entirely by the chain
and air cylinder, supported on the wooden frame «shown in the
drawing. When down in the working positi-on the frame is
supported by the slot-ted hanger. The office of the shield is

to confine the heat from the burners and deflect it toward the
ground, and the heat is so inrtens-e as to kill the weeds, roots
and all.

The burners are made of 3-inch pipe; the construction being
clearly shown in the sectional drawing. The oil comes through
the tube at the center of the burner, and the air blast enters at
the side and passes around the cone at the end of the oil pipe.
The position of the cone may be adjusted by turning the oil
tube, which is threaded where it enters the burner. The air
pipe count-L-ti.on from the car to the burner flame is made by
flexible rubber hose, but the oil pipe attachment required a
packed gland joint, which was made as indicated in the views
of this special fitting.

The supply of oil is carried in an iron tank, holding 1,600
gallons, wliicvh is fitted with a man-hole, and the necessary
